WIP: Fix incorrect default feature value for catboost and added isMuon check with catboost

Mikhail Belous requested to merge fix_cb_feature into master

@dovombru @nkazeev I have tested this code with several different configuration you can check it below and I fix a bug with incorrect default features. Fixing #93 (closed)

Catboost 0:
Muon matching:
Muon fraction in all MCPs: 59295/ 4095296 0.01%
Muon fraction in MCPs to which a track(s) was matched: 5365/ 212348 0.03% \Correctly identified muons with isMuon: 4044/ 5365 75.38%
Correctly identified muons from strange decays with isMuon: 1/ 3 33.33%
Correctly identified muons from B decays with isMuon: 264/ 315 3.81%
Tracks identified as muon with isMuon, but matched to non-muon MCP: 5647/ 206983 2.73%
Ghost tracks identified as muon with isMuon: 492/ 18092 2.72%

Catboost -10:
Muon matching:
Muon fraction in all MCPs: 59295/ 4095296 0.01% \ Muon fraction in MCPs to which a track(s) was matched: 5365/ 212348 0.03%
Correctly identified muons with isMuon: 4780/ 5365 89.10%
Correctly identified muons from strange decays with isMuon: 3/ 3 100.00%
Correctly identified muons from B decays with isMuon: 290/ 315 92.06%
Tracks identified as muon with isMuon, but matched to non-muon MCP: 26297/ 206983 12.70%
Ghost tracks identified as muon with isMuon: 2520/ 18092
13.93%

Catboost -100:
Correctly identified muons with isMuon: 4780/ 5365 89.10%
Correctly identified muons from strange decays with isMuon: 3/ 3 100.00%
Correctly identified muons from B decays with isMuon: 290/ 315 92.06%
Tracks identified as muon with isMuon, but matched to non-muon MCP: 26297/ 206983 12.70%
Ghost tracks identified as muon with isMuon: 2520/ 18092 13.93%

Without catboost:
Muon matching:
Muon fraction in all MCPs: 59295/ 4095296 0.01%
Muon fraction in MCPs to which a track(s) was matched: 5365/ 212348 0.03%
Correctly identified muons with isMuon: 4780/ 5365 89.10%
Correctly identified muons from strange decays with isMuon: 3/ 3 100.00% Correctly identified muons from B decays with isMuon: 290/ 315 92.06%
Tracks identified as muon with isMuon, but matched to non-muon MCP: 26297/ 206983 12.70%
Ghost tracks identified as muon with isMuon: 2520/ 18092 13.93%
